Sorry, I am not in this year - I have a pretty busy summer ahead.

Is this too long? By the way, you can make really nice panoramas if you export the transformed images to TIFF and stitch them together using "enblend". Since blending is not really in our scope, it's probably fine to use that as the final component, if you want a particularly shiny result. Stéfan

Hi all, Working on the scikit-image paper, I've had some further thoughts about authorship (yes, this is much harder than writing the paper :). I suggest the following (what I consider to be) fair guideline: 1) Anyone who contributes significantly to the writing of the paper gets their name in the authors list 2) All other contributors are included in the "scikit-image contributors" author To me, this feels like the fairest way to reward those who time into writing the paper, while also giving credit to all of those whose work is described therein. I felt uncomfortable adding all "core contributors" to the authors list, since that concept is becoming more and more nebulous with GitHub PRs. I'd like to hear your thoughts. Stéfan

I think this is pretty well covered by scikit-learn--check it out! http://scikit-learn.org Cheers StÃ©fan

Re: "Cythonize" not working on OSX?

I didn't know this was a possible course of action! =) I have no idea how many people are affected, or how quick a fix can be... Is it worth exploring a bit more before reversing it? I actually have very little idea about the entire build process so I can't offer much insight here...

Ouch, that's not good: shall we revert that PR and re-open it until we have a chance to investigate? Stéfan

"Cythonize" not working on OSX?
by Juan Nunez-Iglesias 02 Feb '14

02 Feb '14

Hi all, As others have noted (see e.g. here<https://github.com/scikit-image/scikit-image/pull/873#issuecomment-33875298>), the change from using a cython command to the "cythonize" function call within skimage/_build.py has broken the build process on some machines. Cython files don't get compiled to .c files automatically and the build fails with errors such as: clang: error: no such file or directory: 'orb_cy.c' clang: error: no input files clang: error: no such file or directory: 'orb_cy.c' clang: error: no input files Calling Cython manually for all the files works, but obviously this is not a solution. Does anyone know what's going on here? Juan.
